Running Logstash in a Docker container

Logstash receives data from multiple sources, performs data processing, and then sends the log information to the stash, which can mean a store. There are two types of configurations with which to configure Logstash for Docker: pipeline configuration and the settings configuration. We will use pipeline configuration for our demonstration. When the Logstash Docker container runs with pipeline configuration, it will check the path for the logstash.conf file. In our case, the file path is docker_run/pipeline/logstash.conf, as specified in the docker_run_logstash script file. The structure of a Logstash configuration file basically includes three parts: input, filter, and output. You specify the source of the data in the input section, and the destination in the output section. You can manipulate, measure, and create events in the filter section...
